N.J. Stat. Ann. § 44:11-4

4. Upon the filing of a complaint and verified statement as provided by P.L.1964, c.155 (C.44:11-1 et seq.), the court shall proceed in a summary manner to hear testimony for the purpose of determining whether the recipient is functionally incapacitated. The written certification of two physicians who have been in the actual practice of medicine and surgery in this State for at least five years shall be sufficient, but not required, evidence to establish the condition of the recipient. If the court is satisfied that the recipient is functionally incapacitated, the court shall appoint a fit and proper person as representative payee for the recipient.
